There's an extreme likelihood that a JD or an MD wouldn't add any marketability to your portfolio, and instead, would just add an enormous debt load. If you take the LSAT and score 169+ and can get into a T14 (The only law schools worth going to any more) then by all means, go for it. Because in that event, you're likely to get solid job offers outside of pharmaceutical practice/law as well. A JD from any school outside of T14 and maybe T25 isn't worth the paper it's printed on the vast majority of the time.
And MD/PharmD is a waste. I don't believe you'll find a single proponent of that type of dual degree anywhere in industry. I once brought it up to our DoP and she scoffed at it - What's the point, was her main argument.
Even if you could command a $40,000 per year premium on top of your PharmD, would the additional 3 years and incumbent $100,000+ debt (on top of your PharmD debt, yea?) really be worth it?
As far as living in a "shell" - I'm in Nor Calif, one of the most saturated zones for Pharmacy, and there are still jobs. They're not desirable all the time, and they're often prn and such, but they're there. With a JD you might be too specialized, similar to Pharmacists with PGy2 residencies... and may end up working as just a lawyer with an additional doctorate tacked onto your name, you know? In that event, you'll really need that T14 name behind you on your JD 'cos otherwise, there's a million of you all competing for that same job.
Plus I doubt you'll find many decent paying openings for lawyers in your area of NY, also.
